Abstract

A simple physical realization of an integer quantum Hall
state of interacting two dimensional bosons is provided. This is an example of
a "symmetry-protected topological" (SPT) phase which is a
generalization of the concept of topological insulators to systems of
interacting bosons or fermions. Universal physical properties of the boson
integer quantum Hall state are described and shown to correspond to those
expected from general classifications of SPT phases.
